A4
B tier
A4 is an Australian commercial macadamia cultivar associated with modern breeding programs such as Hidden Valley selections. It targets orchard performance and buttery kernel quality for Australia’s large export industry. Flavour is classic creamy macadamia when well handled—selection prioritised farm metrics without abandoning the luxury snack profile. Specify A4 on contracts that track Australian genetics. Judge lots on aroma and style grade fill. Excellent for export snack and baking streams. Keep cool after shelling. Australian numbered and lettered cultivars still require the same oil-care as Hawaiian numbers.

History
A4 type macadamia was selected or named in commercial and orchard practice as growers refined regional stocks.
Orchard and trade grading spread A4 beyond its first districts where climate allowed.
A4 entered wider export catalogues as named-variety marketing grew for nuts.
Specialty buyers continued to request A4 for predictable flavour and size in roasting and baking.
